Abstract
A multi-directional swivel body builder constitutes a bent shank, two sections of joint tube having a ring groove and a lock hole at its far end. The joint tube houses a retaining spring having a turnover leaf and a lock post fitted into the lock hole of the joint tube. The joint tube is inserted into the sleeve tube of the handle. The sleeve tube provides a plurality of adjusting holes. When the joint tube slides in place in the sleeve tube, the catch lug on the inner wall of the sleeve tube will enter the ring groove of the joint tube and press the retaining spring so to allow the handle to move freely along the ring groove for proper angular adjustment. The far end of the handle links with an end wheel. When waving the end wheels with two hands, the bent shank will rotate in cycle.
Description




FIELD OF THE INVENTION




This invention relates to a novel multi-directional body builder, in particular with better bending and diverse changes in angle, which is convenient for the player to play with one hand or two hands.




BACKGROUND OF THE INVENTION




Most of the hand grips are installed with spring in the handle, and the player holds the handle and presses the spring with power in an effort to train the hand muscle. However, such hand grip designed with single spring offers lesser bending angle and more than frequently causes personnel injury. Because it is usually not an ergonomically design, it is hard to fit the height of individual body.




Since the hand grips have failed to give a satisfaction to most players, the inventor has devoted for years to seeking an improvement and come up with a multi-directional swivel body builder.




SUMMARY OF THE INVENTION




The main object of the invention is to provide a body builder with two handles adjustable at any angle to optimize the player's requirements and whole body exercise. The bent shank links with the coil springs at each end, easily to be formed into a perfect full round curve, applicable any part of body without invoking injury.




Another object of the invention is to provide an end wheel, a spacer and a lock shaft at each end of handle and keep a safety gap between the end wheel and the handle. When holding the end wheel and swaying it, the bent shank will begin to rotate. For the eccentric design, the bent shank continues self-rotation due to the centrifugal and inertia force.




The technique, method and performance of the invention are explained in great detail with the aid of embodiments as illustrated in the attached drawings.

DETAILED DESCRIPTION OF THE INVENTION




As shown in

FIGS. 1 through 3

, the multi-directional swivel body builder of the invention mainly comprises a moveable bent shank


1


, two handles


2


, two retaining springs


3


, two end wheels


4


and a protection jacket


6


, where the moveable bent shank


1


is bent inward and links to a coil spring


11


. The other end of the coil spring


11


hooks with two joint tube


12


. The bent shank


1


and the coil spring


11


are wrapped in a protection jacket


6


so to prevent the coil spring


11


from causing personnel injury during the playing. The joint tube


12


has the lock hole


121


and a ring groove


122


at the far end, while the retaining spring


3


can be fixed inside the joint tube


12


.




The retaining spring


3


has a turnover leave and a lock post


31


which will fit in the lock hole


121


of the joint tube


12


. The joint tube


12


is to slide into the sleeve tube


21


of the handle


2


. The sleeve tube


21


provides a plurality of adjustable holes


211


. After the joint tube


12


slides in place in the sleeve tube


21


, the lock post


31


will fit into one hole of the adjustable holes


211


on the sleeve tube


21


. In the meantime, the catch lug


212


on the inner wall of the sleeve tube


21


will slip into the ring groove


122


of the joint tube


12


in order to press the lock post


31


of the retaining spring


3


, allowing the catch lug


212


to move in the ring groove


122


. After the handles


2


have gained the proper angle, the lock post


31


will enter into the adjustable hole


211


to hold the handle


2


steadfast there.




The rear end


22


of the handle


2


connects to a lock shaft


5


, an end wheel


4


and a spacer


41


. The spacer


41


is employed to keep adequate distance from the handle


2


for easy hand operation.




As shown in

FIGS. 4 through 8

, the handles


2


can be operated in multi-directions. Each angular direction can bring an effective effort on hand, chest, arm muscle or abdomen. The handles


2


can be operated in a bending form or in a straight form. The bending form requires less power, while the straight form consumes much more energy. The multi-directional change provokes significant challenges, adjustable in accordance with personal habit.




As shown in

FIG. 9

, the coil spring


11


of the moveable bent shank is bent into a full round curve, feasible to be placed on the neck or the waist without causing any injury.




As shown in

FIG. 10

, when the handles


2


are bent in a relative angle, the end wheels


4


can be bent and swayed. With the axial connection between the lock shaft


5


and the end wheel


4


, when the hands swing, the handles


2


will rotate together with the moveable bent shank


1


. Due to the eccentric design of the moveable bent shank


1


, it continues to self-rotation by the centrifugal and inertia force.




Viewing from the above statement, it is learned that the multi-directional swivel body builder provides better performance, much better than the hand grips. It is an aggressive improvement, justified for a favorable grant of new patent.
